There is no clear data on the chances of the courier being infected with the new coronavirus, as long as it is sterilized in a timely manner the likelihood is relatively small. At present, our country has already appeared due to the courier carrying the virus, resulting in widespread dissemination, so if the courier carries the new crown virus, especially the current Omicron variant strain, which is more transmissible, the transmission pathway is more insidious, it is very likely to cause the spread of the new crown virus. There are no relevant definitive statistics to prove a specific probability. However, during the outbreak, receiving couriers need to take good self-protection measures by using disinfectant solutions such as 75% alcohol to wipe and disinfect the courier’s outer packaging. At the same time, the new coronavirus needs a low survival temperature, as long as the correct sterilization and disinfection measures are carried out, the probability of causing direct infection is relatively small.
